Title: Burner for producing optical oxide powder
Inventor: SHIBUYA SEIJI
IPC: C03B37/018
Filed: 1984-01-26
Abstract: PURPOSE:To produce a soot rod having uniform soot density, in high reproducibility, by using the titled burner composed of a mutually integrated plural unit burners, and reacting the vapor-phase raw material with the flame using said burner. CONSTITUTION:The burner 1 for the production of the powder of oxide for optical use is composed of a plurality of unit burners 2,2..., each having a multi- tube structure and integrated with each other. The burners 2,2... are divided by the outermost walls 3,3... from each other, and share the walls 3a,3a... with the adjacent burner. Polygonal paths of the raw material 4, the oxygen 5 and the hydrogen 6 are formed in the outer wall 3 of each burner 2 from the center outward.
